GAR ROOF.

Original application filed January 10, 1921, fierial No. 135,170.Divided and this application filed February 13, 1923.

T 0 all whom it may concern.

Be it known that I, lVALrER P. MURPHY, a citizen of the United States,residing in New York, in the county of New York and dtat of New York,have invented a new and useful Improvement in Car Roofs, of which thefollowing is a specification.

This invention relates principally to eaves constructions for heavy gagesteel car roofs and is a division of my pending application for patentfor improvement in car roofs, Serial No. 36,170, filed J an. 10, 1921.

The principal objects of the present invention are to obtain awaterproof eaves construction, to protect the bolts that secure the roofto the substructure of the car, to stiffen the eaves ends of the roof,to locate the securing rivets for the eaves ends of the sheet outside ofthe car and to enable the roof to be applied to the car as a unitarystructure. Other objects are simplicity, strength, durability, andtightness.

The invention consists principally in the means hereinafter set forthfor securing heavy gage steel roofs to cars having wood construction;and it also consists in the parts and arrangements hereinafterdescribed. and claimed.

The accompanying drawing, which forms part of this specification is avertical crosssection through the eaves portion of a car roof embodyingmy invention.

The present roof comprises rigid load sustaming roof sheets of heavygage steel, arranged cross-wise of the car and preferably extending fromeaves to eaves there of, The side margins of adjacent sheets are turnedup at right angles forming side flanges 4, which extend from end to endof the roof sheets and merge into the plane of the body of the sheets atsaid ends. Pressed sheet metal seam covers of inverted U- shape incross-section embrace the side flanges 4L of adjacent sheets, and saidseam covers and said flanges are fastened together by horizontal rivets5*. The seam covers 5 are provided with lateral base flanges 6 and havedownwardly curved eaves end portions that merge into the plane of saidbase flanges at the eaves ends of said seam covers. The eaves ends ofthe roof sheets 3 overhang the side plates '7 of the car and are turneddown, as at 8; and the eaves ends of the seam covers are turned down, asat 9,

over the depending eaves flanges 8 ofsaid roof sheets. The upper edge ofthe side sheathing boards 10 terminate below the top of the side plateand are nailed or otherwise secured to the outer face thereof.

The overhanging eaves ends of the roof sheets 3 have one flange of aneaves angle strip 11 rigidly secured. thereto by means of rivets 12, Theeaves angle strip 11 extends lengthwise of the car and is disposed withits lateral flange uppermost and flush with the upper surface of theside plate and extending outwardly therefrom; and the other or verticalflange of said eaves angle strip is suitably secured to the outer sideof the side plate by means of horizontal bolts The lower marginalportion of the eaves angle 11 is bent outwardly over the upper end ofthe side sheathing 10 and thence downwardly over the outer surfacethereof, thereby forming an outwardly offset flange 14 which preventswater and snow from reaching the interior of the car between the sideplate and the sheet.

In the construction illustrated the eaves angle strip acts as means forweatherproofing the joint between the side plate and the side sheathing.

Another important advantage of the hereinbefore described constructionis that the roof sheets can be assembled and riveted to the connectingangle off the car before the same are applied thereto; that is, thewhole roof may be assembled off the car and an plied to the car as aunitary construction. When it is desired to remove a damaged sheet, therivets securing said sheets to said angles can be sheared, as the eavesconstruction allows ample room for cutting and redriving these rivets.if desired, the nuts can be placed on the outside of the caves of theside plate thereby permitting the removal of the eaves angle from theoutside of the car, although, in actual practice, it is preferable tohave the nuts on the inside for the sake of inspection and to enable thenuts to be tightened without removing the fascia.

What I claim is:

1. An eaves construction for car roofs comprising a side plate, metallicroofing extending outwardly beyond the outer face of said side plate,side sheathing secured to the outer face of said side plate with itsupper edge terminating below the upper surface thereof, and an eavesstilfener comprising an angle bar having one flange secured to the outerface of said side plate above said side sheathing and having its otherflange projecting therefrom and rigidly secured to the under side ofsaid roofing, said first 111611- and rigidly secured'to the under sideof said roofing, the eaves end of said roofing being turned down beyondthe outer edgeof the outwardly projecting flange of said angle, and sidesheathing secured to the outer face of said side plate with its upperedge terminating below the upper surface thereof, said first mentionedflange of said angle having an outwardly oil'set portion adapted tooverlap the upper end portion of said side sheathing.

3. An eaves construction for car roofs comprising a side plate,metallicroofing extending outwardly beyond the outer face of said sideplate, side sheathing secured to the outer face of said side Plate withits upper edge terminating below the upper surface thereof, and an eavesstill'ener comprising an angle bar having one flange secured to saidside plate above said side sheathing and having its other flangeprojecting therefrom and rigidly secured to the under side of saidroofing, said first mentioned flange of said angle extending below theupper edge of said side sheathing so as to overlap the same.

4. An eaves construction for car roofs comprising a side plate, metallicroofing, and side sheathing terminating below the upper surface of saidside plate, and an. cares sl-i i fener comprising a member having alateral flange adapted to support the caves end of said metallic roofingand a vertical llang'e secured to said side plate and covering the upperend of said side sheathing.

5. An eaves construction for car roojl's comprising a side plate,metallic rooling, and side sheathing termiiurting below the uppersurface of said side plate, and an eaves stiffener comprising a membersecuri-zd to said side plate and having a laterally extending portionadapted to support lhu eaves end of said metallic roofing and adepending portion covering the upper end ol? said side sheathing.
